Billed as the biggest collection of time travel stories ever, “The Time Traveler’s Almanac” hits bookshelves March 18.

It’s easy to believe publishing house Tor when it claims “The Time Traveler’s Almanac” is the largest and most definitive collection of time-traveling stories ever assembled.

The galley for the book, which arrived in my mailbox last week in a bulbous package more suitable for a pot roast than a work of fiction, is nearly 950 pages of dense, clever, harrowing, funny, insane, brilliant stories from many of the world’s best sci-fi and spec fiction writers.

From late titans to worthy up-and-comers, the book collects more than 70 stories about the liquidity of our perceptual condition from writers Douglas Adams, Ursula K. Le Guin, Ray Bradbury, George R.R. Martin, William Gibson, Richard Matheson, H.G. Wells and dozens more. Edited by Ann and Jeff VanderMeer, the “Almanac” has already earned praise in the U.K. and will be released in the States on March 18.

“So where can I get one?” you ask while you slip on your time-goggles and reflective silver jumpsuit and contemplate the maddening nature of time’s fickle path.
